ABO_3(A=R_(1-x)M_x;B=Mn)型锰氧化物材料中的磁卡效应

Review on the Magnetocaloric Effect in ABO_3(A=R_(1-x)M_x;B=Mn)Type Manganese Oxide Materials

一些锰氧化物具有独特的物理结构以及大的磁卡效应和较宽的磁制冷温区(80-375K),有望成为优秀的制冷工质.从理论和实验两个方面概述了ABO_3(A=R1-xMx;B=Mn)型锰氧化物材料中的磁卡效应,并介绍了典型的ABO_3型锰氧化物磁制冷材料的研究结果.

There has been increased attention to some manganese oxides, because of their unique physi- cal structure,large magnetocaloric effect and broad magnetic refrigeration temperature range （80-375K）, which are likely to become excellent refrigerants. In this paper, the magnetocaloric effect in ABO_3（A=R1-xMx;B=Mn） manganese oxides is summarized from two aspects of theory and experiment,and the research results of magnetic refrigeration of typical ABO_3-type manganese oxide materials are introduced.
